This is an enormous delta, and includes more changes than the deceptively brief changelog entries would suggest. Having looked through the debdiff, I'm not at all confident that this change will have no effect on other already supported modules as you claim; not only do I see a number of rather broad changes to the C code, I also see changes to existing PPDs - there's a lot more to this diff than just adding support for new models.

Would it be possible to backport the new PPDs/filters to the existing version already in hardy? That would be a reasonable change for a freeze exception; but I can't see any way that I would be comfortable with taking this whole diff as a freeze exception.
